Via first-principles electronic structure calculations, we have studied the dependence of the Curie temperature on external hydrostatic pressure for random Ni2MnSn Heusler alloys doped with Cuand Pd-atoms, over the entire range of dopant concentrations. The Curie temperatures are calculated using random-phase approximation to the Heisenberg Hamiltonian whose parameters are determined using the linear response and multiple scattering methods, based on density-functional theory. In (Ni,Pd)2MnSn…

An Ab Initio Study of Pressure-Induced Changes of Magnetism in Austenitic Stoichiometric Ni2MnSn

A quantum-mechanical study of a series of stoichiometric Ni2MnSn structures focusing on pressure-induced changes in their magnetic properties finds both qualitative and quantitative differences in the pressure- induced changes of magnetic moments of individual atoms even for the same global magnetic state.
